Yamaha TT-R230 v8 2015 Owner's Manual

For optimal performance, use a high-quality 4-stroke engine oil with a viscosity rating of 10W-40 or 20W-50. Ensure the oil meets or exceeds the JASO MA standard.
It's recommended to change the oil every 600 miles or 3 months, whichever comes first. Regular oil changes are crucial for maintaining engine health.
The recommended tire pressure is 15 psi for the front tire and 15 psi for the rear tire. Always check the tire pressure before riding for safety.
If the bike won't start, check the fuel level, ensure the kill switch is in the 'run' position, inspect the spark plug for damage, and verify the battery has a charge.
To adjust the chain tension, loosen the axle nut, turn the adjuster bolts on each side to achieve the correct tension, and then retighten the axle nut. Ensure there is about 1.4-1.6 inches of slack in the chain.
Stop riding immediately to allow the engine to cool down. Check the coolant level and inspect for any leaks. Ensure the radiator is not clogged or obstructed.
Remove the seat and air filter cover. Take out the air filter, clean it with a mild detergent and water, let it dry completely, and apply a light coat of air filter oil before reinstalling.
For the first 10 hours, avoid high speeds and excessive loads. Gradually increase speed and load during the break-in period, and check the oil level regularly.
Remove the spark plug cap, use a spark plug socket to unscrew the old plug, and replace it with a new one. Ensure the gap is set to 0.024-0.028 inches before installation.
Regular maintenance includes checking and changing the oil, inspecting the air filter, checking tire pressure, adjusting the chain, and ensuring all nuts and bolts are tight.
